The sonic specialists at Alpine optimize their SPS-410 4" speakers for great range and impressive tone definition, even at low power levels. You can connect these versatile Type-S Series speakers to your factory stereo for an immediate sonic improvement, or hook them up to a powerful aftermarket stereo or amp for increased performance.

Mineral-fortified polypropylene cones are exceptionally stiff, yet lightweight, which means they can push out accurate upper bass and deliver clear midrange. Resilient rubber surrounds help keep the woofer centered for accurate cone movement, reducing distortion. Silk dome tweeters provide warm high notes that bring out the character of the instruments and vocals. Grilles are not included  factory grilles are appropriate for most installations.

Features

Silk Dome Tweeters: Each speaker has a 3/4" Wide-Range
Silk Dome Tweeter for smooth high frequencies.

Efficient Design: The SPS-410's high-efficiency design allows
the speaker to be powered by your factory or aftermarket head unit, resulting in
an easy system improvement for many vehicles requiring 4" or 4x6"
speakers.

4x6 Compatibility: The speakers include adapter brackets which
allow you to mounting them in factory 4x6 locations.

No Grilles: No grilles are included with these speakers.

Great Product

Got these for my husband for Christmas for his beloved '91 4-Runner. He installed 4 speakers and a JVC stereo in about 2 hours. My product advisor at Crutchfield was excellent. I would have to say my experience with Crutchfield was the best on-line experience I've ever had.

Great Speakers for the money! They beat Mercedes factory speakers.

I bought these to replace Mercedes factory speakers in my daughter's W124 300D. We've owned this car since new and the sound system has always been a big disappointment. I should have bought these a decade ago. These were used to replace the factory 4" rear units as well as the the factory 5" front units. The ears on the speakers had to be trimmed using a small cutoff wheel on a Dremel tool in order to make things fit in dash pockets..... but they work perfectly and look like factory... reused factory grills without an issue. I would buy again without hesitation.

Pros:Very nice quality sound for the money. Tonal range is vastly superior to factory Mercedes speakers at about 1/5 the price. Minor tweaks to the mounting ears so that they would fit into the Mercedes speaker factory mounts. I used these to replace the factory 5" front units as well as the factory 4" rear units and they all sound superior to what Benz supplied from the factory.

Alpine SPS-410 in a 2000 Porsche 911

This is the simple solution for us restoration car nuts. Crutchfield recommended these as a direct replacement for all four 4" stock location speakers. Bolt right in, can use stock grills so no mods needed. They sound surprisingly rich, Quite a bargain for me. I'm very satisfied.

Speakers

After having no luck locally finding anyone with speakers that would fit my car or someone to install them I called Crutchfield. They suggested what to buy and how to install them. Guess what, they were a cinch to install and sound great.

Audi owners

AUDI OWNERS BEWARE I Bought these to replace the blown factory speakers in my front doors. The factory ones were 41/2 not 4 and there was no way to mount it with what I was given. I had to go to a audio shop to have them installed by gutting the old speaker and putting the new one in it. Other then that great speakers.

Little speakers that could!

Hey, what can I say, these are Alpines! Legendary Alpine clarity with rich deep lows, great mid range, and infinite highs. These SPS 410s are being used as front speakers in a SAAB 9000 Aero Hatchback. The stereo is simple, a Clarion NZ 500 , two 4" Alpines in the front, two 6" Alpines in the back, a 150 watt Fosgate amp powering a 10" Pioneer sub in the hatch. Not overly complicated but sounds tons better than the factory Bose in my CTS, and Lexus systems. Loud and clear all the way up to max.

1987 Mazda B2000

These little units fit perfectly in my factory location. They have great mid range accompanied with crisp clear highs. I will be building on these by adding 8" under the seat to give a full range sound.

Alpine SPS-410

Used these to replace my worn out OEM rear speakers, on my 93 Toyota, which utilizes Toyota's own speaker boxes with built in amps in the rear on the extracab truck. These fit perfectly with out any modifications and sound great.

huge improvement over factory Porsche speakers

I replaced the factory speakers on my 1999 Porsche 996, both dash and backseat panels, with Alpine SPS-410's. The sound quality was vastly improved and much better than when the vehicle was new. Improvements in the bass was most noticeable but the high ends were clearer and crisper. A great improvement which allowed me to use the original speaker grills.

Pros:Improved bass and high end. Fits in the existing enclosures and allows use of the Porsche speaker grills.

Cons:Minor modifications required to attach the speakers to the grills.

Awesome 4"

Great sounding speakers. Crutchfield said that they would not fit in my car, but after talking to the helpful reps, they allowed me to purchase the speakers and attempt a custom install. With a little modification, they fit flawlessly.

Pros:- Sound great.
- They are Alpines!

Cons:- Lack bass (expected because you should have a sub system with these)

2002 Chevy Camaro w/ Monsoon

Wonderful upgrade to existing back hatch speakers. Crutchfied was incorrect though. It said they would not fit my vehicle, but with a little cutting of the plastic trim panels, these fit right in the factory location.

4" Alpine dash replacement speakers for 88 toyota p/u

There were only a couple that would fit in the factory holes in the dash.Quick and easy install and the sound is great. The radio/disk player is Blaupunkt no amp needed.all around great sound

Great Jeep Wrangler Pod Speaker Replacement

Written By Brandon, Texas on Friday, September 23, 2011

I used these in the stock Rubicon 7 speaker system. Removed the tweeter and woofer from the pods in the dash and sound way better than any 5 1/4 you would stuff in there without an enclosure. These are much nicer sounding and less distorted. The mids are there too. Dont expect bass but they do breakup less than the 5 1/4 with plates mounted in the same location.

The stock speakers have bass blockers stock inside the enclosure cut the green and black wires off the stock speaker and solder the new alpines into the bass blocker wires, green is NEG and black is POS. Not to be confused with the plug wires in the dash, they are black red/brown LEFT and Violet/Blue on he Right. I am talking about the wires in the 7 speaker system Pods.

Get these for the Wrangler! I got a great deal on these. They are a steal!

Nice little speakers

We bought these to replace the original rear speakers in my wife's 1984 Porsche 911. The original sound system had never worked well. We put a new Kenwood HD receiver in dash and a set of the Alpine SPS-510s in the door. What a difference. You can actually hear the music even with the top down. For less than $300 we put a great sounding system into her car. Very clear and sharp sound. Since the car is a convertable we didn't want to go overboard with the system since weather and theft are much more of a problem in a drop top. Very satisfied with the product and the service we received from Crutchfield.

Nice Little speakers!

I installed these in the rear doors off my Subaru along with the 6-3/4" component system and Alpine deck and they sound great. Everybody knows you can't expect much bass from a 4" speaker but these little dudes keep you rockin' down the highway with good sound and they are very inexpensive!

Very nice sound

Written By Brandon, Mobile,AL on Thursday, July 28, 2011

I bought these speakers to replace the dash speakers on my 2003 Jeep TJ, and all I can say is that these speaker give a great sound despite their small size. Any genre of music sounds very good through them and comes through crisp and clear.
